我已经按照此处所述使用 snap 包安装了 go 1.11: https: //github.com/golang/go/wiki/Ubuntu# This will give you the latest version of go$ sudo snap install --classic go一般情况下运行良好,但是,当我尝试编译一个使用 的项目时cgo,出现以下错误:/snap/go/2635/bin/go test -c -i -o /tmp/__...

On Unix systems, Remove/RemoveAll will work even if the files are chmod 0600. On windows, Remove/RemoveAll will not remove a file marked as read-only. If you want to write a Go program that deletes a file, you need to take special care o...
从fofa中搜索RDP,会看到它会解析出RDP的信息。 本文探索如何自己实现一个。 Nmap指纹 在https://raw.githubusercontent.com/nmap/nmap/master/nmap-service-probes可以找到关于RDP发包的定义 ###NEXT PROBE### This is an RDP connection request with the MSTS cookie set. Some RDP# listeners (with NLA?) ...

本从以go-1.16版本源码为基础,介绍了defer关键字的使用规则、实现原理和优化路线,最后介绍了几种将近的使用场景。试图对 go defer 关键字应用到实现原理有一个全面的了解。 defer 概述 Go 提供关键字defer处理延迟调用问题。在语法上,defer与普通的函数调用没有什么区别。正如官方文档描述的那样: ...
基于BIO 存在的问题,我们进行一轮改进,核心是将 read 操作由同步阻塞操作改为带有尝试性的非阻塞操作. 在读一个 fd 的时候,倘若 io event 已就绪就正常读取,否则就即时返回并抛出一个特定类型的错误,让 loop thread 能够正常执行下去,为其他 fd 提供服务. ...
